Nice one! That looks like it was WELL corroded in!

Lol, yeah I don't want to risk using it because it's paper thin. I think with a half-moon shaped shim bonded into that side it'll be nearly as good as new again.

The good news is the derailleur cleaned up nicely and under the grime it’s in really good mechanical condition: The bad news is that it’s a completely different size! Digging around the internet, it looks like there were English and French versions of these early Cyclo derailleurs. The...

Potentially yes to all of that. We know that early on English riders weren’t keen on alloy components because they could be fragile compared to steel counterparts. The steel Cyclo could either have been a cheaper model or it could have been the same thing but destined for the UK market? There’s...

Filthy Cyclo has arrived: It is indeed filthy and a bit gummed up. I haven’t got the original with me so I can’t do a direct comparison, but this looks like an all-steel version of the one that was on the bike. So it’s got a steel arm, steel nuts and a steel lower jockey wheel instead of an...

Yes, right forum! Quickest way to date it might be via the Sturmey Archer hub. They have a number stamped into the shell which is the production date. Some just have two digits which is the year, some have four digits which is the month and year...

I used to have a late 30s BSA Sports and this bike is quite similar. I did a lot of detective work on mine so I might as well pass on a bit of that knowledge here. I'm glad you found a Hercules marking because there were a lot of these factory-built Roadster and Sports bikes made by...

Quite a few people on here have had success with them. As long as you put the correct chamfer on the inside of the bb shell I think they’re fine 👍 @Mark Manley if you want some dimensions highonbikes has an eBay store. You’re likely to get a response on there.

Yes, this is completely normal.

Brilliant news!

No it doesn’t. It’s rusty but where the hell are you getting rusted through at bb joint from? Crank looks like a what style? There aren’t any cranks in any of the pictures. 7/8” seatpost? That would be 22.2mm. That’s not even a size. Am I missing something here?

These shifters look like they’ll strip down like the old Dura Ace ones did. I’d get in there with the tools and see what’s stuck/missing/unlatched/broken* *delete as appropriate I’d do that first. If you decide to go the route of using 7 gears off an 8-speed cassette, I’d strongly recommend...

I think you’ll get a better purchase pulling on the bars, especially with your natty soft jaws that fit the fork! 3D printed? Hold the fork higher up near the crown so it all flexes a bit less. Sorry if I’m stating the obvious!

BEFORE YOU CUT THE STEM! Have you definitely whacked the wedge out? Did you undo the bolt in the quill a couple of turns and give it a couple of sharp hits with a hammer and feel the wedge come loose? If it’s still jammed in the bottom of the quill you’re going to struggle to get it out. My...

Any indication why a Czech bike shop has so many old French bikes? Presumably pulling them out of barns and part-restoring them is good business, but are they coming from barns in France or Czech Republic?
